Adding field with filename when merging shapefiles with ogr2ogr?

With small scripting it would be doable. With something like following you should be able to add column to a shapefile in all shapefiles in a folder, and merge them to merged.shp file

for %f in (*.shp) do (
  ogrinfo %f -sql "ALTER TABLE %f ADD COLUMN filename character(15)"
  ogrinfo %f -sql "UPDATE TABLE %f filename = '%f'"
  ogr2ogr -update -append merged.shp %f -f “esri shapefile” -nln merge 
)

edit: The same as a Bash script, with some changes to make it working:

for f in *.shp
do 
  base=${f%.shp}
  ogrinfo $f -sql "ALTER TABLE $base ADD COLUMN filename character(15)"
  ogrinfo $f -dialect SQLite -sql "UPDATE $base SET filename = '$base'"
  ogr2ogr -update -append merged.shp $f
done

I would use the -sql option, and import the shapefile in the following way:

ogr2ogr -update -append %destination% %n2% -sql 'SELECT "%n2%" as SHAPE_ORIG, field1, field2, ... FROM %n2%'

there are some ways for merging shapefiles.

• if you want to merge layers as a one layer, you can use MMqgis tools for merging...

---

• if you want to merge all shapefiles under a folder, you can use DARREN COPE simple code here.

---

mkdir merged
for %f in (*.shp) do (
if not exist merged\merged.shp (
ogr2ogr -f “esri shapefile” merged\merged.shp %f) else (
ogr2ogr -f “esri shapefile” -update -append merged\merged.shp %f -nln Merged )
)

• beside this can use GeoMerge free tool for merging lots of file but dont forget to consider your file size for workin with it.

and adding attribute to shapefile @dango directon is good. you can use layer.CreateField(field_name) for creating a new column which is populated from

import os
shapeFileName = os.path.splitext("your_shape_file_path")[0]

i hope it helps you...
